OK, so my shortblock build uncertainty path is now certain. I bought a standard bore 340 block cast in 1969. Included is a steel crank and rods. No pistons. Also included is the windage tray. I will bore to 4.07", and not look back. I do have a question. The main caps had normal hex bolts. Caps 2/6 did not have extenders for tray. A quick look at Hughes, and I can get an ARP entire set for over $100. Why so freaking much? Any other options? Is finding just the 2 cap bolts with extenders difficult, and if i do, is it crazy to mix them with old?
Going .040" over versus .020" over to get a few more cubes won't do much.
Spreadsheet is perfect.Not a problemo... It is in Excel. You want it in an email? Send me a PM.
I have 7-8 columns for various SBM combinations. The weight data has been gathered from a variety of sources.
Or would type of stuff be useful to post 'out in the open'? I can do a screen capture and post it.
Conventional wisdom and experience is that a cast crank is good for somewhere in the 400+ HP range. I personally would not bet on the Mancini cast crank to be any particular level of quality without knowing more about it.
If you start with a 340 crank and use SCAT or Eagle I-beam rods with KB pistons, you are going to be taking a lot more weight off of the crank for balancing than if you start with a 318 or 273 crank. I don't see a crank on Mancini for under $353...??? I personally would just put the 318 cast crank in there.
